Holder for adjustable magnetized dowel pin stop

Abstract

A U-shaped holder includes free ends which may be adjustably drawn together by an adjustment bolt such that a bushing positioned in a cavity formed in the free ends is adjustably clamped. A magnetized dowel pin is eccentrically positioned in the bushing. A locater pin may be positioned in the lower end of the cavity and be urged downwardly by a spring between the dowel pin and the locater pin. The bushing is of non-ferrous material to shield the locater pin from the magnetic dowel pin.

What is claimed is: 
     
       1. An adjustable dowel pin stop comprising, a dowel pin holder having a cavity,   a dowel pin eccentrically positioned in a bushing,   said bushing rotatably positioned in said cavity,   means on said bushing for selectively adjustably rotating said bushing and said dowel pin, and   said holder including a spring-loaded locater pin on the bottom side thereof and said locater pin normally extending downwardly and outwardly to be received in a locater hole and being adjustable to be depressed upwardly and inwardly into said holder.   
     
     
       2. The structure of claim 1 wherein said dowel pin is formed from magnetic material. 
     
     
       3. The structure of claim 2 wherein said bushing is of non-ferrous material to shield said locater pin from being magnetized by said dowel pin. 
     
     
       4. The structure of claim 1 wherein said holder is U-shaped and bolt means is provided for adjustably moving the free ends of the legs of said U-shaped member towards and away from each other and said cavity is formed by said free ends of said legs whereby said bushing is adjustably clamped by said leg free ends. 
     
     
       5. The structure of claim 4 wherein a locater pin is positioned in said cavity below said dowel pin and a spring in said cavity urges said locater pin downwardly and outwardly of said holder. 
     
     
       6. The structure of claim 5 wherein one end of said spring engages the lower inner end of said dowel pin and the other end engages the inner upper end of said locater pin and an enclosed head is provided on said locater pin to limit outward travel in the cavity.
